Objectives: The purpose of this study was to investigate users of non-contact healthcare service and analyze associated factors including sefl-efficacy of healthy behaviors and digital health literacy. Methods: In 2022, an online survey of adults(age 19~69) was conducted to investigate non-contact healthcare service utilization for more than one month during the last three years. The non-contact healthcare services included tobacco smoking cessation, alcohol consumption management, healthy diet, physical activity, walking, weight control, and mental health. A total of 2,759 respondents were included in the analysis. We used four questions for positive self-efficacy measures and compared the responses with perceived effectiveness of the non-contact services and 15 item digital health literacy measures. Results: Utilization of non-contact services increased from 2019 to 2022. Physical activity and weight control services were more likely used than other services. Digital Health Literacy(DHL) scores were positively related to self-efficacy of health behaviors and subjective effectiveness of the six different health care services. Conclusions: Utilization of non-contact healthcare service was highly associated with increased self-efficacy and digital health literacy.
